Wireframes please :)
so good man, looks swish!
Not sure if you're texturing this or not. I would say the shader is too reflective right now. Also, the physical sun thing is bleaching out your renders, i'm not a fan of that way of lighting scenes. Try lighting it with simple Three point lighting and an Ambient Occlusion pass ( you should know how to do this I think ) and combine the two in PS. I expect it will make your model pop a lot more.
This was just a test. It's not representative of the final render and texture
